meet UL1950 and EN60950-1 safety standards. The combination of the UMP's higher

efficiencies and thermally conductive potting compound enables these devices to

achieve higher operating temperatures without derating. The 2" x 3" UMP "footprint"

conforms with the standard pinout and pin geometries of most 3" x 3" devices (a

33% space savings) while delivering as much as 60% more power (40W vs. 25W).

UMP Model DC/DC’s operate from four input voltage ranges (10-36V for "Q12"

models, 18-36V for "D24" models, 18-75V for "Q48" models, and 36-75V for "D48"

models). Available output voltages are 5, 12 and 15 Volts.

automatic assembly to construct the UMP’s traditional, field-proven, SMT-on-pcb

designs. Devices employ corrosion-resistant metal cases with plastic headers. Heat

generating transformer cores and power semiconductors are mounted directly to the

cases, which have threaded inserts for add-on heat sinks or pcb mounting. Devices

are specified for –40 to +100°C operation and derating information is provided for

operation with/without heat sinks and forced air flow.

output overvoltage protection, output current limiting, and thermal shutdown. UL,

CSA, EN and IEC compliance testing is currently in progress (75V-input devices will

be CE marked) as are full EMI/EMC characterizations. Contact DATEL for the latest

available information.

... UMP Model DC/DC Converters are classified, by output power, into 25, 30, 35 and 40 Watt devices. For the single-output devices listed above, the RoHS-6 maximum available output power is the product of the nominal output voltage compliant* and the maximum allowable output current indicated within the part number (see Part Number Structure) ...

... Common (pin 8) for normal usage or the positive side (+Output, pin 9) to effectively reverse the output polarity. Filtering and Noise Reduction All UMP 25-40 Watt DC/DC Converters achieve their rated ripple and noise specifications without the use of external input/output capacitors. In critical applications, input/output ripple and noise may be further reduced by install- ing electrolytic capacitors across the input terminals and/or low-ESR tanta- lum or electrolytic capacitors across the output terminals ...
